Rerupture after treatment of acute Achilles tendon rupture is considered a serious complication. Yet data on long-term outcome after rerupture are limited. This study evaluated outcome after rerupture and compares it to a reference of uncomplicated cases. Thirteen patients with a rerupture following minimally invasive surgical Achilles tendon rupture repair were evaluated using Leppilahti score and resumption of work and sport. Mean follow-up was 8.7 years. Results were compared with a reference group of 23 uncomplicated cases with a follow-up of at least 1 year. The study was designed as a follow-up study. The relative risk for a fair/poor outcome by Leppilahti score after a rerupture when compared with uncomplicated cases is 2.83 (95% confidence interval=1.17-6.87; P=.0185). Although rerupture did not affect ultimate resumption of professional life, the relative risk for quitting sport or resuming sport at a lower level after a rerupture is 3.33 (95% confidence interval=1.71-6.51; P=.0001). In contrast, the plantar flexion strength deficit is 5% to 10% in the rerupture group and up to 20% in the reference group. Despite sufficient recovery of calf muscle strength, rerupture after acute Achilles tendon rupture treatment results in significant long-term functional disabilities. Copyright
